Add an implementation of this, moving the common call to tpm_init() up
into the common API implementation.

Add a test.

4fef657151 tpm: Separate out the TPM tests for v1 and v2
Currently there is only one test and it only works on TPM v2. Update it
to work on v1.2 as well, using a new function to pick up the required
TPM.

Update sandbox to include both a v1.2 and v2 TPM so that this works.
Split out the existing test into two pieces, one for init and one for
the v2-only report_state feature.

1b11de766f test: add a test for the new tpm_auto_start() function
A prior patch adds a new API function for TPM2.0, which performs
the full startup sequence of the TPM.  Add a selftest for that.

3bb4db4c38 tpm: Allow reporting the internal state
It is useful to read information about the current TPM state, where
supported, e.g. for debugging purposes when verified boot fails.

Add support for this to the TPM interface as well as Cr50. Add a simple
sandbox test.
